Class

Represents an arc with a set center, direction, angular range, and X/Y radius.

Definition

Package:@progress/kendo-drawing

Methods

addObserver

Adds an observer to be notified for changes.

Parameters:observerGeometryObserver

The observer to add.

Returns:

Arc

  • The current Arc instance.

bbox

Returns the bounding box of this arc after applying the specified transformation matrix.

Parameters:matrixMatrix

The transformation matrix to apply.

Returns:

Rect

  • The bounding box after applying the transformation matrix.

getAnticlockwise

Gets the anticlockwise flag of the arc.

Returns:

boolean

  • The anticlockwise flag of the arc.

getCenter

Gets the center location of the arc.

Returns:

Point

  • The location of the arc center.

getEndAngle

Gets the end angle of the arc in decimal degrees. Measured in a clockwise direction with 0 (zero) pointing "right".

Returns:

number

  • The end angle of the arc.

getRadiusX

Gets the X radius of the arc.

Returns:

number

  • The X radius of the arc.

getRadiusY

Returns:

number

  • The start angle of the arc.

observers

Returns the list of observers.

Returns:

GeometryObserver[]

  • The current observers.

pointAt

Gets the location of a point on the circumference of the arc at a given angle.

Parameters:anglenumber

The angle in decimal degrees. Measured in a clockwise direction with 0 (zero) pointing "right". Negative values or values greater than 360 are normalized.

Returns:

Point

  • The point on the circumference of the arc.

removeObserver

Stops notifying the specified observer for changes.

Parameters:observerGeometryObserver

The observer to remove.

Returns:

Arc

  • The current Arc instance.

resume

Returns:

Arc

  • The current Arc instance.

suspend

Suspends the change notifications to all observers.

Returns:

Arc

  • The current Arc instance.
